MOUNT CLEMENS, MI -- Kathy Ladd, a 62-year-old Mount Clements woman, ran some errands Sunday. When she returned to Park Place Tower Apartments, the senior living complex she lives at in Mount Clemens, Ladd found that her mobility scooter had been stolen from the lobby, Macomb County sheriff's officials say.

After hearing the story, an anonymous donor purchased Ladd a scooter that Macomb County officials plan to present at 1:30 p.m. Thursday.

The estimated value is $4,000.

Investigators from the Macomb County sheriff's office distributed surveillance images of a man riding away from the complex on Ladd's "prized red-and-tan scooter," Macomb County officials say.

The suspect remains at large. Anyone with information is asked to call Detective Jason Abro, 586-307-9364.
